Chapter 2486: Released

As the development of Huangsha Town is getting better and better, countless peeping eyes are also coming in. For these people, Lin Ze can’t take them directly. After all, if he wants to develop Huangsha Town, Linze must open Huangsha Town If you really leave these people, Huangsha Town will not develop.
　　 There are a lot of people, and this problem of people's heart is a big problem. One is not good, and it will come up with things that are very difficult to clean up.
　　For example, those children of the royal family, depending on their identity as the royal family, are here to do prestige and blessing.
　　 Someone here will say that even the top royal descendants like Yan Zifeng dare not cause trouble in front of Lin Ze, so why do other royal characters dare to make trouble?
　　 The reason is actually very simple, that is, these royal children have not yet reached that status, they only know some fur.
　　 And because they only know some furry things, when bad things happen, they are definitely there.
　　 They would call themselves the disciples of the royal family, and asked Lin Ze for this, and for that, it would be strange if there was no problem for a long time.
　　 is not only the royal children, but also the family, sect, etc., there will always be some people who can't see themselves clearly, or say that they have very high self-evidence, and they will be troubled by Lin Ze.
　　 Therefore, in order to avoid such troubles, Lin Ze simply simply let everything go and let these people know what they are facing now, whether he or they have the ability to deal with it.
　　Similarly, this is also a kind of support for those who want to take root in Huangsha Town, an invisible spiritual protection.
The stronger the strength and heritage displayed by Lin Ze, the stronger the ability to withstand risks in the future. Correspondingly, the more peaceful they live in Huangsha Town, then they will of course settle in peace of mind. In Huangsha Town, peace of mind has developed here.
　　 is precisely considering these, so this time Lin Ze simply opened the door, let everyone see their magic.
　　 In the end, this effect was also expected to be good. The first furnace steel just just scared countless people.
　　Just the first furnace, it directly produced more than 20,000 pounds of pig iron ingots. Moreover, this output is less than one-third of a day's output. Such a number really frightens countless people!
　　 Those who are present are very clear that the war is actually fighting material. Now the iron factory on Linze can produce so much steel in a day. It can be said that Linze has taken the absolute upper hand from now on.
　　Once there is a war, Lin Ze can easily form an extremely powerful steel army.
　　 As soon as he thought of the need to face such a powerful steel army in the future, all the people present were chilling.
The amount of pig iron was enough, and Hu Yan quickly ordered the staff around him to close the trench used for casting, and then opened the trench leading to the iron furnace, and the molten iron flowed into the iron furnace that had been burned for half an hour. inside.
　　 Obviously, Hu Yan is ready to start ironing.
　　 The appearance of the reflective iron stove looks like a teacup of Kung Fu tea. However, the bottom and wall of this teacup are hollow. The molten iron is directly installed in the cup, and the coal is burning at the bottom of the cup. The flame produced by the combustion passes through the arched teacup wall of this kung fu cup, reflecting the heat into the cup, continuously heating the molten iron, and then removing the remaining flame from the chimney.
The chimney was buried directly under the groove where the molten iron flowed just after it left the furnace. This is to preheat the molten iron, and the next section is entangled with the intake air duct and the blower is inside. The fresh air coming from outside keeps warming up, and finally the flue gas with lower temperature is discharged into the air.
In this way, the temperature is continuously increased, the molten iron in the furnace is heated, and the molten iron preheated into the furnace groove is preheated to warm the air blown into the bottom combustion chamber. These procedures are carried out in sequence, burning in order, flame It is also in this way that the last trace of its residual heat is used until it finally turns into a ray of blue smoke and dissipates in the air.
　　This is the maximum utilization of the residual combustion temperature, but also to save energy and reduce pollution.
The vegetation around Huangsha Town is really poor. It can be said that it can’t tolerate any pollution here. It was already a semi-desert zone. Lin Ze has finally recovered some of its vitality now. If it is because of the pollution of the steel plant Emissions have directly destroyed the ecology here, so Linze might as well not build this ironworks.
　　Compared to steel, the bad environment is more important to Lin Ze.
　　Do not look down on the sewage equipment built by Lin Ze, thinking that the current situation of Shenzhou Continent, these sewage equipment is actually better than not, because it is too backward.
　　 However, in fact it is not the case, because there are refining masters on Lin Ze's side, there are them, using refining means, and some formation methods to arrange some means of reducing pollution, it is still very simple.
　　For example, like the problem of dust reduction, Hu Yan directly set up several arrays of dust reduction techniques here, and the problem of dust reduction here was solved.
So, don’t look at the technical level of Linze’s steelmaking plant, which is still far behind those in later townships//towns// places. However, in terms of environmental protection and energy conservation awareness, Linze’s side A lot ahead.
There is a special organization, so the fuel in the iron-making furnace is completely separated from the molten iron, so that you can use coal with confidence, or even dig it directly, which is much lower than the cost of charcoal that needs to be burned in the kiln. Anyway, because these coals are isolated, they do not need to be in contact with the molten iron inside. In this way, the sulfur and phosphorus in the coal will not be mixed into the molten iron, which directly improves the quality of the molten iron.
　　 At this time, the molten iron was continuously heated, and the light of the stars was glowing-it was caused by the small mixed in the molten iron.
　　 Seeing this, Hu Yan directly started the mixing equipment in his hand. The large disc on the top of the furnace began to rotate slowly, driving the three wrought iron sticks in the molten iron to circulate and stir continuously.
At the beginning, the carbon content of the pig iron melted in this blast furnace should be about 3%. Now, after being stirred by these wrought iron sticks, the carbon in the molten iron directly reacts with the oxygen in the air at high temperatures. The reaction produces carbon dioxide and emits a lot of heat.
　　 All of a sudden, the molten iron inside boiled the pot, and the bubbles continued to go straight, even pushing the on the surface to the side of the furnace to pile up.
The melting point of pig iron is generally around 1100-1200 degrees Celsius, while pure iron is as high as 1535 degrees. When the carbon in the molten iron and the oxygen in the air begin to combine, the carbon content in the pig iron is gradually reduced, and the temperature of the molten iron is also continuously increased. Correspondingly, its melting point is gradually increased, so in the iron furnace The molten iron becomes very thick.
　　 From the beginning just like a clear soup, to the sauce state afterwards, and then from the sauce state to the final jelly state...
　　 Eventually gathered into a very cute shape of iron balls. From a distance, it looks like a shot, it has a sense of quality.
　　 These poor "shots" don't know yet, they will be beaten soon.
　　 After the stirring was stopped, the workers picked up the shots with long pliers and placed them under the forging hammer for continuous beating.
Ding Ding Dang, the carbon element in the iron mass was squeezed out in the form of elemental graphite, together with the fine scum inside and the iron oxide debris on the surface, because it also contains some high temperature residual temperature, so once it came out After the cold air outside, it turned into a spark in the air.
　　 This forging is just to remove some impurities, the process is actually very simple, anyone can do it, that is, with a pair of pliers, under the forging hammer, hitting a few times, there are no other special requirements.
In addition, in fact, wrought iron is very soft at high temperatures, so it is easy to shape and easy to forge, but no, for a long time, the workers around Hu Yan have all shapes in their works, discus, iron Stick, iron ball...
　　 Until Hu Yan could not see it, it was also for the convenience of management. Finally, he announced that he would be knocked into an iron rod in the future, and no other shapes could be made at will.
　　Although wrought iron is easy to forge, the process of forging wrought iron is more labor-intensive. The wrought iron is also iron, and tens of pounds of iron, it still takes a lot of strength to clamp it.
　　 In addition, it takes considerable effort when forging, so this thing is not so easy.
Fortunately, there are a lot of workers here, plus the ability to work here as a worker has a lot of strength, so soon ~EbookFREE.me~ All the wrought iron is being played by special people, and , The speed is not slow.
The so-called "wrought iron" that has been beaten and beaten is not actually wrought iron in the sense of modern textbooks.
In fact, there is no such thing as raw iron or wrought iron in the metallurgical industry. In the modern iron and steel industry, wrought iron is called domestically in China with a carbon content of less than 0.02%, and pure iron in foreign countries. The texture is very soft; the carbon content is 0.02% －2.11% is called steel; domestic with carbon content above 2.11% is called pig iron and foreign countries is called cast iron.
　　In ancient times, pig iron smelted directly from iron ore in a blast furnace was called "cooked iron" after being smelted in an iron furnace (steel furnace). The carbon content of this "cooked iron" is inversely proportional to the smelting time. The longer it is fried, the more carbon is oxidized. The lower the carbon content of iron, and vice versa, so its carbon content can be between 0.01% and 1.5% Floating includes "pure iron" and "steel" in the modern sense.
　　 So the ancient stir-fried iron is equal to the stir-fried steel, but because of the above-mentioned problems in the process, it is difficult to grasp some of these problems, and the resulting finished products are mainly iron and low-carbon steel.
　　 Of course, if you leave the dog//shit//luck//, you can run into one or two pieces of high carbon steel.
　　 But this probability is almost the same as the chance of winning a lottery now.
　　 Sincerely don't hold much hope!
